Wood stove

Abstract

The heating stove comprises from top to bottom, a smoke space, an oven, a combustion chamber and an ash-pit; a grate separates the chamber from the ash-pit. The grate comprises a plurality of open-ended hollow cylindrical metallic ducts which criss-cross so as to form a X and which open outwardly of the stove for heating ambient air circulating therethrough. Each of the ducts has a substantially-flattened crossing portion, in order to reduce the spacing between the tubes. The grate may support a solid combustible, but permit the ashes to drop into the ash-pit between the ducts. A plurality of upright semi-cylindrical tubes are fixed to the sides of the oven and form passages between the combustion chamber and the smoke space. The oven is heated not only at its bottom but along its side walls and the tubes also serve to heat the ambient air.

What I claim is: 
     
       1. A stove comprising an enclosure having a front wall, a rear wall, top and bottom walls, and two side walls, a smoke outlet made in said top wall, an upper and a lower partition fixedly mounted to said walls in vertically-shaped relationship within said enclosure, intermediate and parallel to said top and bottom walls, a smoke space, and a cooking oven space being defined above said upper partition and between said upper and lower partitions, respectively, a grate extending within said enclosure intermediate said lower partition and said bottom wall, a combustion chamber and an ash-pit being defined above and below said grate, respectively, an air intake for said combustion chamber, said grate comprising a plurality of hollow cylindrical metallic ducts, which criss cross in order to form an X and which open outwardly at each end, the ends of each duct extending through and fixed to said side walls permitting the ambient air to circulate through said ducts; each of said ducts having an intermediate crossing portion that is substantially flattened, said grate being able to support a solid combustible, yet allowing therethrough by gravity the cinders into said ash-pit; a plurality of lateral semi-cylindrical upright pipes closed at both ends and fixedly secured to and projecting from the exterior face of each of said side walls between said top wall and the outer ends of said ducts, said side walls having first and second openings making communication between said combustion chamber and said pipes and between the latter and said smoke space, respectively. 
     
     
       2. The stove as defined in claim 1, wherein said air intake comprises intake control means consisting of two triangular flaps covering said air intake and pivoted to said stove and to one another at their apex at a pivotal point corresponding to the criss-crossing center of the ducts, and tongues integral to said flaps and permitting to close or open said air intake in a progressive fashion. 
     
     
       3. The stove as defined in claim 1, wherein said cooking oven comprises an access door having at least one rocker flap permitting the progressively-increasing production of heat outwardly therefrom. 
     
     
       4. The stove as defined in claim 1, wherein the crossing portion of the said ducts is flattened at both opposite sides of the duct, except for the two ducts at each end of said grate for which the crossing portion is flattened on a single side.
